Radial Piston Pump PR4-3X/20,00-500RA12M01 - Bosch Rexroth R901093852

High pressure in an open circuit calls for stiff piston guidance. This radial piston pump works with 10 pistons and a constant displacement of 20 cm³, delivers 26.5 l/min and holds operating pressure up to 500 bar.

Benefits

• Operating pressure up to 500 bar from 10 radially arranged pistons, rated for HLP hydraulic fluid.
• 26.5 l/min flow at a constant displacement of 20 cm³.
• Cylindrical shaft end Ø 25 mm with fitting key to ISO 3019-2, clockwise rotation.
• 4-hole fastening with 63 mm centering to connection diagram 1.
• Cast iron housing and NBR seals at 16.78 kg weight.
• Version without through-drive for single drive on one motor.

Application

The pump feeds clamping and pressing tools, test rigs and power units in open circuit. Constant delivery suits machines where flow is metered by valves rather than by the pump itself. The Ø 25 mm shaft end with fitting key allows mounting to standard electric motors.
